OK help me understand this.
I have 2 users in my linux system that are BOTH part of "web-users" group.
one is www-data used by the webserver and php-cgi
one is my ftp-user
when I upload files via ftp they are set to 775 for dirs and 664 for files, when I run a script on the server (so same group like the ftp user) to delete that directory and files inside: unlink for files works ok but the command rmdir doesnt work returning permission denied!?
why is that 775 means that the group's user can delete it just like 664 for files.
